我尝试获取表格的内容并将其放入新窗口进行打印，但我发现此错误： 该表在一个模态中，它通过ajax函数返回到模态动态：
这是ajax函数：
function view(id){
var html;
$.ajax({
url: "<?php echo site_url('admin/prescription/view_prescription_ajax') ?>/"+id,
type: 'POST',
dataType: 'html',
success:function(data){
html = data;
},
async: false
});
$('#view .modal-body').html(html);
$('#view').modal('show');
}
这是此代码返回的htmt

这是javascript
function printData()
{
var divToPrint=document.getElementById("printTable");
newWin= window.open("");
newWin.document.write(divToPrint.outerHTML);
newWin.print();
newWin.close();
}
答案 0 :(得分：0)
您应该成功调用打印数据，因为在dom内容添加到dom之后事件没有绑定。 也不要忘记从按钮属性
中删除onClick =“printData”'detailchecked'
